Yes. Will be fixed in the re-roll.

Yes, I agree that limiting by #commits, or by pack size would be more
intuitive. However, neither of those values are available to me at the point
where I have to decide what to do with the pack data (only the pack header
is available, and that only contains the object count).

Agreed. Will be renamed to receive.objectCountLimit in the re-roll.
